Students are introduced to the carbon cycle through discussion, modeling and a game. Students then complete activities and investigations on Greenhouse gasses, photosynthesis, cellular respiration and ecosystem services (functions and values of...(View More) intact ecosystems to humans). The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard."(View Less)

This unit consists of two parts, each with several activities which require students to participate in investigations, discussions, computer data analysis, role-playing, and research. In Part 1, students examine the roles of Earth's energy balance...(View More) and the greenhouse effect in creating and affecting climate. Part 2 focuses on the biosphere as a system. Students examine the interactions of organisms, the effects of climate change on food webs, and the importance to humans of a healthy, intact ecosystem. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard."(View Less)

Designed as a five-lesson curriculum to introduce students to limnology, this program explores the structure, history and biology of lakes. Students analyze models, images, and a core sample from a lake case study before engineering a device for...(View More) collecting lake bottom sediment samples. The curriculum includes a guide, handouts, images, resources and a pre- and post-assessment.(View Less)

In this activity, student teams will create a controlled experiment by building ecosystems in two 2-liter bottles. Teams determine the control conditions of both bottles, identify a test variable, and run the experiment for several weeks to...(View More) determine the role of the test variable in the system. The experiment uses living organisms such as aquatic plants or pond water microorganisms, a pH and ammonia test kit, light source and thermometer. Questions assessing understanding are provided. This resource is supported by Chapter 1, "What is Global System Science?" part of Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.(View Less)
